This process ensures that the exchange rate is representative of real market transactions, guaranteeing transparency and stability for companies and individuals that operate with currencies.

The determination of the FIX is carried out every banking business day starting at 12:00 p.m.and is officially published in the Official Gazette of the Federation (DOF) the next day.

What is the difference between the Bank of Mexico exchange rate and the market price?

The main difference between the exchange rate of the Bank of Mexico (Banxico) and the market price is the way they are calculated and used:

Banxico (FIX) exchange rate:

• It is a reference rate that the Bank of Mexico determines and publishes daily, usually around noon.
• It is calculated from a weighted average of quotes collected from the wholesale exchange market during three specific periods in the morning, considering operations that reflect prevailing market conditions.
• The FIX serves to resolve payment obligations in foreign currency, banking operations, contracts and settlements, and is the official reference in billing and institutional operations.
• It remains fixed until the next business dayso it is not updated in real time, and is usually more stable.

Market price (spot, bank, over-the-counter exchange rate):

• It is the value at which dollars are actually bought and sold in banks, exchange houses or financial platformsand may differ between institutions.
• This price varies constantly during the day according to supply and demand, economic expectations, monetary policy, news, and international factors.
• It is usually a little higher for the public because it includes commissions, profit margin, operating costs and risk, which is why at the counter it is higher than the FIX, and each bank offers different purchase and sale prices.

Therefore, when you consult a bank price, there is usually a difference of cents (sometimes greater) compared to the FIX value. The FIX helps provide order and transparency to the Mexican market, but it does not determine the final price of each individual operation.

If the US inflation turns out to be lower than expectedas happened today, generates the expectation that the Federal Reserve (Fed) could cut interest rates or not upload them soon. This weakens the dollar against other currencies and generally strengthens the Mexican peso.
